comm mxm To all whom it may concern Be it known that I, EUGENE BROWN, a citizen of the United States, residing at Colfax,.in the county of Whitman and State of Washington, have invented a new and useful Concrete-lWixer, of which the following is a specification.-

This invention relates to concrete mixers,

one of its objects being to provide a tiltable drum with which is combined a carnage mounted in a novel manner and having special means whereby, when the drum is tilted, the carriage is caused to move toward and from the drum along a track provided therefor, thereby to direct a delivery chute into and out of the drum.

' With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof-theinvention herein disclosed,'ca nbe made within the scope of what is claimed, without departing from the spirit'of the invention.

In the accompanying drawings the pre ferred' form of the invention hasbeen shown.

' Insaid drawings Figure 1 is a side elevation pf the machine, the drum being shown tilted to discharging position. 4 I f Fig. 2 is a plan view, the drum being shown in horizontal position."

Fig. 3 is a section through a portion of the machine andshowing the drum in upwardly inclined or receiving position.

Fig. 4 is a section on line AB Fig. 3. P Fig. 5 is an elevation of the outer end portion f the feed chute, its supporting platform being shown in section.

Fig. 6 is a perspective view of the 006perating portions of one side of the Wheel supported structure andits extension platform, said parts being detached from each other.

Fig. 7 is aside elevation of a portion of the barrel rotating mechanism at the side of the machine opposite to that shown in Fig.1.

motion is transmitted through a pulley 4 and belt. 5 to a pulley 6 secured to a short shaft 7 journaledupon one side portion of the structure 1. Secured tothis' shaft so as to rotate therewith and with the pulley 6 is a sprocket 8 for the purpose hereinafter set forth.

Arranged within the upper portion of the structure '1 are side strips 9 having trunnions 10'alining'withthe shaft 7 and which trunnions'are journaled on' the structure 1. Side strips 9 are connected at their ends by means of cross strips 11, to the sides of rectangular frames 12 on which are journaled anti-friction rollers 13. In the lower corner portions of these frames are journaled supporting rollers 14. J ournaled upon the upper cross strips 11 is a transverse shaft'15 to which is secured a sprocket 16 adaptedto receive motion through a chain 17 from the sprocket 8\ on shaft-7.' A bevelgear 18-is secured to the shaft- 15 and meshes with a gear 19 secured to ashaft 20 which is journaled on one of the frames-12 and also upon an extension frame 21 which is secured to said frame 12 and moves therewith. A

sprocket 22 is secured to the shaft20 and is adapted'to transmit motion-through a chain 23 to a sprocket 24 secured to a'stud 25 extending at right angles from a plate 26. This plate'is adapted to be attached to head 27 of a wooden barrel 28, one end ofthe barrel being open and said barrel being extended through the frame 12. Detachably mounted on the barrel atopposite sides of the center thereof are rings 29 having inwardly extended flanges, said rings being preferably made of T-irons. Bolts 30 connect the rings and are'arranged betweenthe wall of thebarrel and the inwardly extending flanges on the rings. Said inwardly extending flanges are adapted to be engaged by the supporting rollers 14 and by additionalside rollers 31 oonnectedito the sides ofthe frames 12. The'rollers 13 bear against thei outwardly extending portions of the rings. Thus the various rollers provide saidbarrel can rotate freely within the frame and will, at the same time, be held against 2 longitudinal displacement relative thereto.

A shaft 32 is journaled in the structure 1 and is provided with radial arms 33 and
